Given numbers are 729,370,290,818,970
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,370,290,818,970 is 310328950410.
Find LCM of 729,370,290,818,970 with Prime Factorization
| 2 | 729, 370, 290, 818, 970 |
| 5 | 729, 185, 145, 409, 485 |
| 729, 37, 29, 409, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 729 x 37 x 29 x 409 x 97 = 310328950410
Therefore, the lowest common multiple of 729,370,290,818,970 is 310328950410.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
729 x 370 x 290 x 818 x 970 = 62065790082000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
729 : 1, 3, 9, 27, 81, 243, 729
370 : 1, 2, 5, 10, 37, 74, 185, 370
290 : 1, 2, 5, 10, 29, 58, 145, 290
818 : 1, 2, 409, 818
970 : 1, 2, 5, 10, 97, 194, 485, 970
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,370,290,818,970, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
370:2x 5x 37
290:2x 5x 29
818:2x 409
970:2x 5x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 5 = 200
Therefore, the value for common factors is 200.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 62065790082000/(1x200)
LCM = 62065790082000/200
LCM = 310328950410
Thus, we can understand that the LCM of 729,370,290,818,970 is 310328950410.
